Hey folks, on the latest SVN version of GameData, and the latest compiled .exe I could find (8555), I am experiencing a game-breaking bug where after a sector receives reinforcements, a turn or three later I can no longer select mercs or groups, or click cancel, on the Strategic Map screen. The list on the far left is clickable, rest of the UI is responsive, but the small dialog when selecting a merc or a group in a sector cannot be interacted with.

This is my current long term save (50% progress), as I just met Mike. After attacking a sector, 1 turn after reinforcements arrive I can no longer select mercs on the Strategic Map. Also interesting is that I can't click Cancel at the bottom of the dialog.

I've painstakingly played and replayed from old saves to determine the trigger for this issue, and it only seems to happen a few turns after enemy reinforcements arrive at a sector that I am attacking, after they are alerted to my presence. I am a chronic restarter of this game... probably 20 campaigns over the years as I restart when things get easier, but this is my longest running playthrough and I would love to actually finish the end game with the new features.

Has anyone seen anything like this? Any ideas where the bug may be located? I can continue to progress in my save only with Spy/Stealth kills, but this is frustrating.

I can attach a save, but it currently says that I am limited to 0kb, possibly because I have a low post count?

Got the latest exe to compile! On starting my save prior to the bug, I get the following debug message in the game log (bottom of tactical screen)

However, with this latest SVN exe, after exiting tactical to test selection of groups, I can open the sector where the battle is occurring, but when I select "Go To Sector" I hear a click but nothing happens. Weird. But, I am able to get back to the action with the down arrow button next to the laptop.

Haven't figured out the difference yet, but I have encountered a situation where simultaneously:

I can't select a group or merc on the strategic map from the dialog, nor can I click 'Cancel'
I can't exit the dialog with Escape, but can left click elsewhere on the strategic map to dismiss the dialog
Can click "Go to sector" to try to continue the fight, but if I hit the down arrow button, or hit Escape a couple of times I can get back in the fight.

Was able to step through the code finally using "Break All", and got to step through CreatePopUpBoxForMovementBox, which runs the first time you open the dialog, and then runs again when you've clicked on a person, setting the asterisks around their name to show selection.

When the bug occurs, CreatePopUpBoxForMovementBox occurs for the first paint, but when you then try to select the group or merc, the second CreatePopUpBoxForMovementBox does not fire, as if my click didn't go through.

However, the mouseover highlights work properly - anything under my cursor is changed to white, including the Cancel option. Just can't get a click to register.

While the game progress is paused, typically only opening the laptop and shutting it will cause the bug to occur, where I cannot select a group, merc, or click cancel from the Strategic Map. If once doesn't work, try opening the laptop screen again a couple of times.

Opening the options menu doesn't seem to be enough, but opening the save menu seems to tip things over the edge.

I have also had other button oddities, though not frequently. Rarely, sometimes Group and Cancel will be unclickable, but the lone merc name is selectable.

@Flugente, you seem to have had experience in this space, any ideas how I could monitor / find this resource? Is MouseRegions barking up the wrong tree?

Would you be willing to open this save and see if you have the same outcome?
